David Klaasen
Just had a new boiler installed and the lads that did the work were friendly, knowledgeable, professional and very helpful with minimising disruption while doing the job. They are a great team. Very happy to highly recommend.
Derek Newman
Tuesday morning I woke up to a cold house and checked the heating and saw that the pressure in the system was low and upped the pressure to the recommended level thinking I had cured the problem . However it failed to cure the problem so contacted AJS who came out early next morning and cured the problem in less than half an hour. As usual prompt and efficient Service from the engineer. Highly rec=mmend company, been using them for over 15 years.

Absolutely recommend AJS. They installed a Air source heat pump and complete plumbing for our new build. Everyone was friendly, polite and helpful. Always cleaned up and took away rubbish. The office ladies always helped with our inquiries. The whole job experience went well and would definitely use them again.

Serious lack of knowledge of heat pumps and consequent misdiagnosis of an issue. They really should pull out of of this area of business.

Frequently asked questions
How do I know you’re properly qualified and certified to install heat pumps?
We are MCS‑certified and registered with an approved consumer protection/competent person scheme, which is essential for quality assurance and to access grants like the Boiler Upgrade Scheme (BUS).
Can you tell me if a heat pump is actually suitable for my home?
We carry out a detailed home assessment, including property type, insulation levels, existing heating system and available outdoor space, to confirm whether a heat pump is a good fit.
What type and size of heat pump will you recommend for my property, and why?
We design the system using a heat‑loss calculation for your home, then match the correct kW size and model (for example, air‑source vs ground‑source) so it runs efficiently and reliably.
What will the full installation cost be, and what’s included in your quote?
Our fixed quote clearly lists the heat pump, cylinder, controls, labour, scaffolding (if needed), electrical work and any radiator or pipework upgrades, so you know exactly what you’re paying for.
Can you help me access government grants like the Boiler Upgrade Scheme?
Yes, as an MCS installer we can confirm your eligibility, apply for the BUS grant (worth up to £7,500) on your behalf and deduct it directly from your quote.
How much disruption should I expect during installation, and how long does it take?
A typical air‑source heat pump installation takes around 2–5 days, and we’ll agree locations for the indoor and outdoor units, manage any planning considerations and keep you informed each day.
Will I need to replace my radiators or upgrade anything else in my home?
After the heat‑loss survey, we’ll advise if any radiators, pipework, electrics or hot‑water cylinder need upgrading so the system can run efficiently at lower flow temperatures.
How noisy is the outdoor unit and where will it be installed?
Modern heat pumps are designed to be quiet and must meet UK noise regulations; we’ll position the unit to minimise any impact on you and your neighbours and comply with local planning rules.
What warranties, servicing and aftercare do you provide?
You’ll get manufacturer warranties on the heat pump plus our workmanship guarantee, and we offer ongoing servicing and support to keep your system performing at its best.
What running costs and savings can I realistically expect compared to my current boiler?
We’ll estimate your likely annual running costs and potential savings based on your current fuel type, insulation level and tariffs, using real‑world performance data rather than lab figures.
